I claim: In a traction attachment, a traction frame adapted to bemounted below the body of an automobile and secured to the axlehousings,-

traction wl1ee]s supporting the rear end of nections between thefriction wheels and the itraction' wheels for driving the tractionwheels.

In testimony whereof I have signed my name to this specification.
